In this episode of Car Trek Series 5, AutoTempest challenges the guys to drive each others' dream cars. Simple, isn't it? Well, Ed's drive in the Aston Martin DBS brings back some less than favorable memories, Tyler ponders whether a manual Lamborghini Murcielago LP640 really is worth $200,000 more than an automatic one, and Freddy has some very choice words for the SLS AMG. There may be a fist fight involved.
